Lion 10.7.2 crash with Espionage

I started to see this really nasty issue a few weeks ago, now it is getting really a problem. I am basically using Espionage to have my mail folders encrypted and nothing more. Sometimes when I start Espionage (and only when I start Espionage my system completely freezes and I get the following traces:

My system then becomes only accessible per SSH and the only thing I can do is a shutdown which after 15 minutes has still has not completed.
I have a second little issue, but nothing compared to the crash one. I have Growl 1.3.1 on my system, but Espionage does not recognizes it, nor can it use it.
Your help is greatly appreciated.
